<p>Don’t stress about summer activities. I never did a pre-college program or anything like that, and I was accepted to Harvard and several other Ivies.</p>
<p>I spent my summer before senior year working as a counselor at a local day camp, training for cross-country, looking at colleges, and having fun with friends and family.</p>
<p>That being said, it helps if you can show that you had at least a little bit of intellectual stimulation over the summer. For example, I was interested in programming, so I watched online Computer Science lectures. Something like that will give you something to talk about if a question about your summer comes up in an interview.</p>
